EXPLOSION-MOTOR,-

- To all whom it may concern .rotary valve so incased as to be Be it known that I, LEON L. RussELL, a citizen of the United States of America, and resident of New Rockford, in the county of Eddy and State of North Dakota, have 1nvented certain new and useful Improvements in Explosion-Motors, of which the following is a specification.

This invention relates to explosive engines and particularly to rotary valves for controlling the delivery of the explosive charge to the cylinders of a motor and exhausting the gases therefrom after the explosion;

An object of this invention is to EIOVHIG a eely rotatable in the casing and so arranged with relation to the said casing that pressure on the said rotating member will be equalized on two sides, a condition which will prevent undue friction of the parts, or binding while the valve is rotating.

A further object of this invention is to provide a combined exhaust duct or pipe and valve casing, the same being coupled with the heads of cylinders in such a -wa as to make them readily demountable so t at the interior structures may be accessible for all purposes. v

A still further object of this invention is to provide a valve having ports of such a structure or. configuration as to insure efliciency in the delivery of the charge and permitting a rapid exhaust of the spent gases or products of combustion.

With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will .be had to the accompanying drawings forming part of this specification wherein like characters denote corresponding parts in the several views, and in which I v Figure 1 illustrates a view in elevation partly in section, showing the motor with the invention applied thereto;

Fig. 2 illustrates a sectional View on the line 2--2'of Fig. 1; and

Fig. 3 illustrates a sectional view on the line 33 of Fig. 1.

In these drawings 5 denotes the cylinders of a motor which may be applied to any crank casing 6, the exact construction of Specification of Letters Patent.

Application filed November 2, 1915. Serial No. 59,252.

these parts being immaterial and therefore are not described in detail. There is acrank shaft or other driving device 7 provided with a valve driving connection and for convenience of illustration, the sprocket chain 8 is shown as engaging the sprocket wheels 9 and 10, the latter of which is on the valve shaft 11 so that the valve shaft is positively driven through a coupling 11 and it may be coupled and properly timed with relation to the drive shaft 7. It is the desire of the in-. ventor that the showing of the means for driving the valve shaft be regarded as only a conventional illustration and these features may include any well known or preferred connection or gearing for accomplishing the result.

The valve casing 12 for each cylinder preferably constitutes a part of the head of the cylinder, the head being indicated by the numeral 13, there being ports 14 leading from the valve casing to the cylinder, one port being shown on each side of the said casing.

The rotary valve comprises the side disks 15 and 16 mounted on a section of a hollow shaft 17, that portion of the hollow shaft between the disks bein cut away to form an aperture 18 by whic the explosive charge enters the valve casing.

. The space between the two disks-is partially inclosed by radially extending walls flared port through which the explosive charge passes from the tubular shaft. The sides of the rotary valve have apertures 22 of irregular contour, each of said apertures having its outer wall curved so that it is parallel with the periphery of said disk. The side walls of each aperture are converted and merge with the inner wall which is likewise convexed, thus giving to the walls of the aperture an irregular outline in which the area of the aperture increases gradually from the side edges to the center, a construction which has been found efficient in admitting the explosive charge to the ports 14 to the best advantage. The rotary valve is suitably packed so that the explosive charge cannot escape from the. or- ;tion of the valve just descrlbed except w on the apertures of the valve register with the ports 14 and this insures proper delivery of the explosix e charge to the cylinder.

As a means for effecting an exhaust from the cylinders, each rotary valve has its sides provided with apertures 23 and when these apertures come into registry or alinement with the ports 14, the exhaust is effected and said exhaust escapes to the exhaust pipe 24 which mayv be superimposed with relation to the valve casing or may form a part thereof according to the ideas of the producer.

By reason of the fact that there is a very large area of the valve devoted to the exsleeves. There is a coupling 27 between the ends of the shafts in each sleeve and this coupling has ports 28 for the admission of the explosive charge so that said explosive charge passes from the intake manifold to the sleeve and to the coupling, from whence it finds its way into the hollow shaft and the rotary valve.

It is believed that a rsum of the opera tion of the device is unnecessary in view of the fact that the functions of the several parts have been ascribed to them during the description of the said parts, and it follows that if the valves are suitably rotated and an explosive charge is delivered to the intake manifold, the said charge will be delivered to the cylinders and that upon ignition of the charge, the exhaust will be effected through the apertures and ports and the exhaust manifold, as stated. It will furthermore be apparent that there will be equal pressure on the surfaces of the disks forming part of the valve to obviate undue friction or binding of the parts.
